Description

Technical Field

[0001] The embodiments of the present application relate to image display technology, and more specifically, to a field sequential display device and an image display method. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, people have higher requirements for the display effects of display devices. The field sequential display method can not only improve the saturation of the displayed image, but also reduce power consumption.

[0003] In the prior art, for field sequential display, a frame of color image to be displayed is split into multiple single-primary color images according to color, and a frame display time is divided into multiple sub-field sequences corresponding to the single-primary color images. The single-primary color image is displayed in the corresponding sub-field sequence, and multiple single-primary color images are quickly switched within the display time of one frame, and color display is achieved by using the persistence of vision effect of the human eye.

[0004] However, because each pixel in a field sequential display device includes multiple sub-pixels, when displaying a single primary color image, each pixel corresponds to a color data, and the multiple sub-pixels included in the pixel all display the color corresponding to the color data, resulting in a lower resolution of the displayed image. Summary of the invention

[0005] The embodiments of the present application provide a field sequential display device and an image display method, which are used to solve the problem in existing display methods that all of the multiple sub-pixels included in each pixel display one color, resulting in a low resolution of the displayed image.

[0006] In a first aspect, an embodiment of the present application provides a field sequential display device, the field sequential display device comprising: a display screen and a processor, the processor being configured to:

[0007] Receiving an image to be processed, and splitting the image to be processed to obtain a plurality of single-primary-color images;

[0008] Determine an initial grayscale value corresponding to a pixel point according to the single primary color image;

[0009] Determine a target grayscale value corresponding to a sub-pixel point included in the pixel point according to an initial grayscale value corresponding to the pixel point and initial grayscale values ​​corresponding to pixel points adjacent to the pixel point;

[0010] Generate image data to be displayed according to the target grayscale value corresponding to the sub-pixel point;

[0011] The display screen is configured to: according to the image data to be displayed, control the backlight source corresponding to the primary color of the single primary color image to light up, and control the liquid crystal molecules corresponding to the sub-pixel points to deflect to a target angle.

[0012] The beneficial effects of this embodiment are as follows: after receiving the image to be processed, the processor first splits the image to be processed to obtain multiple single-primary-color images; then for each single-primary-color image, the initial grayscale value corresponding to each pixel is determined according to the single-primary-color image. Then, according to the initial grayscale value corresponding to each pixel and the initial grayscale value corresponding to the pixel adjacent to each pixel, the target grayscale value corresponding to the sub-pixel included in each pixel is determined, and the image data to be displayed is generated. Finally, according to the image data to be displayed, the display screen controls the backlight source corresponding to the primary color of the single-primary-color image to light up, and controls the liquid crystal molecules corresponding to the sub-pixel to deflect to the target angle to display the image. This solution determines the target grayscale value corresponding to each sub-pixel included in each pixel, so that the same pixel can display multiple colors, effectively improving the resolution of the displayed image.

[0013] In some embodiments of the present application, before the processor is used to split the image to be processed to obtain multiple single-primary-color images, it is also used to:

[0014] Get the image to be processed and the operation mode;

[0015] Among them, the operating mode is a first operating mode or a second operating mode, the first operating mode represents a mode of operating at a preset refresh rate, and the second operating mode represents a mode of operating at a refresh rate N times the preset refresh rate, wherein N is greater than 1.

[0016] The beneficial effects of this embodiment are as follows: by acquiring the operating mode before splitting the image to be processed so that the data to be displayed can be subsequently generated according to the operating mode, the resolution of the image displayed according to the data to be displayed is effectively improved while meeting the refresh rate requirement.

[0017] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel point included in the pixel point according to the initial grayscale value corresponding to the pixel point and the initial grayscale value corresponding to the pixel point adjacent to the pixel point, it is specifically used to:

[0018] If the operation mode is the second operation mode, the pixel points are divided into target row pixel points belonging to the target row and non-target row pixel points not belonging to the target row;

[0019] Determine a target grayscale value corresponding to a sub-pixel point included in the pixel point in the target row according to an initial grayscale value corresponding to a pixel point in the target row and an initial grayscale value corresponding to a pixel point adjacent to the pixel point in the target row;

[0020] Determine the target grayscale value corresponding to the sub-pixel point included in the non-target row pixel point according to the initial grayscale value corresponding to the pixel point adjacent to the non-target row pixel point;

[0021] If the operating mode is the first operating mode, the pixels are not divided into target row pixels and non-target row pixels, and the target grayscale value corresponding to the sub-pixels included in the pixel is determined based on the initial grayscale value corresponding to the pixel and the initial grayscale value corresponding to the pixels adjacent to the pixel.

[0022] The beneficial effects of this embodiment are as follows: when the operation mode is the second operation mode, the pixel points are divided into target row pixel points and non-target row pixel points, and then the target grayscale values ​​corresponding to the sub-pixel points included in the two are determined in different ways. When the operation mode is the first operation mode, the target grayscale values ​​corresponding to the sub-pixel points included in the pixel point are determined directly according to the initial grayscale values ​​corresponding to the pixel point and its adjacent pixel points. According to different operation modes, the target grayscale values ​​corresponding to the sub-pixel points included in the pixel point are determined, so that the determined target grayscale values ​​are more accurate.

[0023] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel included in the pixel point according to the initial grayscale value corresponding to the pixel point and the initial grayscale value corresponding to the pixel point adjacent to the pixel point without dividing the pixel point into the target row pixel point and the non-target row pixel point, it is specifically used to:

[0024] Determine a target sub-pixel point from the sub-pixel points included in the pixel point;

[0025] Using the initial grayscale value corresponding to the pixel as the target grayscale value corresponding to the target sub-pixel;

[0026] For sub-pixels to be configured except the target sub-pixel among the sub-pixels included in the pixel, determining a reference pixel corresponding to the sub-pixel to be configured from pixels adjacent to the pixel;

[0027] The target grayscale value corresponding to the sub-pixel point to be configured is determined based on the first distance between the sub-pixel point to be configured and the target sub-pixel point included in the pixel point, the second distance between the sub-pixel point to be configured and the target sub-pixel point included in the reference pixel point, the initial grayscale value corresponding to the pixel point, and the initial grayscale value corresponding to the reference pixel point.

[0028] The beneficial effects of this embodiment are as follows: when the operating mode is the first operating mode, the sub-pixels included in the pixel point are divided into target sub-pixels and sub-pixels to be configured, and then the initial grayscale value corresponding to the pixel point is used as the target grayscale value corresponding to the target sub-pixel point; the target grayscale value corresponding to the sub-pixel point to be configured is determined according to the two distances from the target sub-pixel point included in the pixel point and the reference pixel point, and the initial grayscale value of the pixel point and the reference pixel point, so that the target grayscale value corresponding to the determined sub-pixel point is more accurate, and when the sub-pixel point is displayed according to the target grayscale value, the display effect is better and the color transition is smoother.

[0029] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel to be configured according to the first distance between the sub-pixel to be configured and the target sub-pixel included in the pixel, the second distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel, the initial grayscale value corresponding to the pixel, and the initial grayscale value corresponding to the reference pixel, the processor is specifically used to:

[0030] Determine, according to the magnitude relationship between the first distance and the second distance, a first weight corresponding to the pixel point and a second weight corresponding to the reference pixel point, wherein the sum of the first weight and the second weight is 1;

[0031] The product of the initial grayscale value corresponding to the pixel point and the first weight and the product of the initial grayscale value corresponding to the reference pixel point and the second weight are added together to obtain the target grayscale value corresponding to the sub-pixel point to be configured.

[0032] The beneficial effects of this embodiment are as follows: based on the size relationship between the first distance and the second distance, the weights corresponding to the pixel point and the reference pixel point are determined, and then the target grayscale value corresponding to the sub-pixel point to be configured is calculated in combination with the initial grayscale value corresponding to the pixel point and the reference pixel point, so that the target grayscale value corresponding to the determined sub-pixel point is more accurate.

[0033] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel point included in the target row pixel point according to the initial grayscale value corresponding to the target row pixel point and the initial grayscale value corresponding to the pixel point adjacent to the target row pixel point, it is specifically used to:

[0034] Determine a target sub-pixel point from the sub-pixel points included in the pixel point;

[0035] Using the initial grayscale value corresponding to the pixel point in the target row as the target grayscale value corresponding to the target sub-pixel point included in the pixel point in the target row;

[0036] For sub-pixels to be configured other than the target sub-pixel in the target row of pixels, a reference pixel corresponding to the sub-pixel to be configured is determined from pixels adjacent to the target row of pixels;

[0037] The target grayscale value corresponding to the sub-pixel to be configured is determined based on the third distance between the sub-pixel to be configured and the target sub-pixel included in the target row of pixels, the fourth distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel, the initial grayscale value corresponding to the target row of pixels, and the initial grayscale value corresponding to the reference pixel.

[0038] The beneficial effects of this embodiment are as follows: when the operating mode is the second operating mode, the pixel points are divided into target row pixel points and non-target row pixel points, and then the target row pixel points are divided into target sub-pixel points and sub-pixel points to be configured, and then the target grayscale values ​​corresponding to the two sub-pixel points are determined, so that the target grayscale values ​​corresponding to the determined sub-pixel points are more accurate, and when the sub-pixel points are displayed according to the target grayscale values, the display effect is better and the color transition is smoother.

[0039] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel to be configured according to the third distance between the sub-pixel to be configured and the target sub-pixel included in the target row of pixels, the fourth distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel, the initial grayscale value corresponding to the target row of pixels, and the initial grayscale value corresponding to the reference pixel, the processor is specifically used to:

[0040] Determine, according to the magnitude relationship between the third distance and the fourth distance, a third weight corresponding to the pixel point in the target row and a fourth weight corresponding to the reference pixel point, wherein the sum of the third weight and the fourth weight is 1;

[0041] The product of the initial grayscale value corresponding to the target row pixel and the third weight and the product of the initial grayscale value corresponding to the reference pixel and the fourth weight are added to obtain the target grayscale value corresponding to the sub-pixel to be configured.

[0042] The beneficial effects of this embodiment are as follows: based on the size relationship between the third distance and the fourth distance, the weights corresponding to the target row pixel points and the reference pixel points are determined, and then the target grayscale values ​​corresponding to the sub-pixel points to be configured are calculated in combination with the initial grayscale values ​​corresponding to the target row pixel points and the reference pixel points, so that the target grayscale values ​​corresponding to the determined sub-pixel points are more accurate.

[0043] In some embodiments of the present application, when the processor is used to determine the target grayscale value corresponding to the sub-pixel point included in the non-target row pixel point according to the initial grayscale value corresponding to the pixel point adjacent to the non-target row pixel point, it is specifically used to:

[0044] According to the initial grayscale values ​​corresponding to the pixel points adjacent to the non-target row pixel point, a preset high refresh rate method is adopted to determine the target grayscale values ​​corresponding to the sub-pixel points included in the non-target row pixel point.

[0045] The beneficial effect of this embodiment is that by processing the initial grayscale values ​​corresponding to the pixel points adjacent to the non-target row pixel points using a preset high refresh rate method, the target grayscale values ​​corresponding to the sub-pixel points included in the non-target row pixel points can be obtained more accurately.

[0046] In some embodiments of the present application, the preset high refresh rate method is a two-line gate line DLG method or a hardware super-resolution HSR method.

[0047] Beneficial effects of this embodiment: The target grayscale value corresponding to each sub-pixel point in the non-target row of pixels is determined using the DLG method or the HSR method, so that the target grayscale value corresponding to the determined sub-pixel point is more accurate.

[0048] In a second aspect, an embodiment of the present application provides an image display method, including:

[0049] Receiving an image to be processed, and splitting the image to be processed to obtain a plurality of single-primary-color images;

[0050] Determine an initial grayscale value corresponding to a pixel point according to the single primary color image;

[0051] Determine a target grayscale value corresponding to a sub-pixel point included in the pixel point according to an initial grayscale value corresponding to the pixel point and initial grayscale values ​​corresponding to pixel points adjacent to the pixel point;

[0052] Generate image data to be displayed according to the target grayscale value corresponding to the sub-pixel point;

[0053] According to the image data to be displayed, the backlight source corresponding to the primary color of the single primary color image is controlled to light up, and the liquid crystal molecules corresponding to the sub-pixel points are controlled to deflect to the target angle.

[0054] The beneficial effects of this embodiment are as follows: after receiving the image to be processed and the operating mode, the image to be processed is first split to obtain multiple single-primary-color images; then for each single-primary-color image, the initial grayscale value corresponding to each pixel is determined according to the single-primary-color image. Then, the initial grayscale value corresponding to each pixel, the initial grayscale value corresponding to the pixel adjacent to each pixel, and the target grayscale value corresponding to the sub-pixel included in each pixel are determined to generate the image data to be displayed. Finally, according to the image data to be displayed, the backlight source corresponding to the primary color of the single-primary-color image is controlled to light up, and the liquid crystal molecules corresponding to the sub-pixel are controlled to deflect to the target angle to display the image. This solution determines the target grayscale value corresponding to each sub-pixel included in each pixel, so that the same pixel can display multiple colors, effectively improving the resolution of the displayed image.

[0065] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0066] Based on the exemplary embodiments described in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the claims attached to this application. In addition, although the disclosure in this application is introduced according to one or several exemplary examples, it should be understood that each aspect of the disclosure can also constitute a complete implementation method separately.

[0067] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0068] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise indicated. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, for example, they can be implemented according to orders other than those given in the diagrams or descriptions of the embodiments of this application.

[0069] In addition, the terms "including" and "having" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0070] With the development of technology, the way to achieve color display in liquid crystal display devices has evolved from filter layer display to field sequential display. In a liquid crystal display device using filter layer display, each pixel includes multiple sub-pixels, and the sub-pixels include filter layers of corresponding colors. The light emitted by the backlight source passes through the filter layer to form colored light, which can then display a color image.

[0071] For example, Figure 1 A schematic diagram of the structure of a field sequential display device for performing field sequential display provided by the present application, such as Figure 1 As shown, the field sequential display device includes a main board and a display screen. The processor in the main board is connected to a timing control (TimingController, abbreviated as: TCON) board in the display screen. The TCON board is connected to a liquid crystal panel in the display screen. The liquid crystal panel includes backlight sources corresponding to multiple primary colors and liquid crystal molecules corresponding to each sub-pixel.

[0072] Depend on Figure 1 It can be seen that the field sequential display device that performs field sequential display does not require a filter layer. The field sequential display splits a frame of color image to be displayed into multiple single-primary color images according to color, and divides a frame display time into multiple sub-field sequences corresponding to the single-primary color images. The single-primary color image is displayed in the corresponding sub-field sequence. Multiple single-primary color images are quickly switched within the display time of one frame, and color display is achieved by using the visual persistence effect of the human eye. The backlight source can provide a monochrome backlight corresponding to the sub-field sequence for the liquid crystal display panel. In the sub-field sequence, the liquid crystal molecules in the liquid crystal panel are driven and moved to the position corresponding to the single-primary color image; then the backlight source corresponding to the primary color of the single-primary color image is controlled to light up to realize the display of the single-primary color image in the corresponding field sequence. The saturation of the displayed image can be improved, and power consumption can also be reduced.

[0073] However, because each pixel in a field sequential display device includes multiple sub-pixels, when displaying a single primary color image, each pixel corresponds to a color data, and the multiple sub-pixels included in the pixel all display the color corresponding to the color data, resulting in a lower resolution of the displayed image.

[0074] For example, Figure 2 The color data diagram of the sub-pixel points corresponding to the color image provided in this application; Figure 2 As shown, Figure 2 Each square in the image represents a sub-pixel, and a pixel includes three sub-pixels. For example, sub-pixels with color data of R11, G11, and B11 constitute a pixel. Among the sub-pixels corresponding to the color image, the color data of the sub-pixels included in a pixel are different, namely, the color data corresponding to red, the color data corresponding to green, and the color data corresponding to blue.

[0075] The color image can be split into single primary color images. Based on the above example, Figure 3 The color data diagram of the sub-pixel points corresponding to the split single-primary color image provided in this application is as follows: Figure 3 As shown, the color image can be split into three single-color images. Figure 3The first color data image from top to bottom is the color data image of the sub-pixel points corresponding to the single-primary color image with the primary color of red, the second color data image is the color data image of the sub-pixel points corresponding to the single-primary color image with the primary color of green, and the third color data image is the color data image of the sub-pixel points corresponding to the single-primary color image with the primary color of blue. In the color data images of the sub-pixel points corresponding to the single-primary color image, the sub-pixel points included in the same pixel point correspond to the same color data, and the multiple sub-pixel points included in the pixel point all display the color corresponding to the color data, which will cause the problem of low resolution of the displayed image.

[0076] In view of the problems existing in the prior art, the inventors discovered during the process of studying the image display method that in order to improve the resolution of the displayed image, for the same pixel, the sub-pixels in the pixel can display different colors corresponding to the same single primary color to improve the resolution. After obtaining the image to be processed, for each single primary color image, determine the initial grayscale value corresponding to each pixel; then, based on the initial grayscale value corresponding to the pixel and the initial grayscale value corresponding to the pixel adjacent to the pixel, determine the target grayscale value corresponding to the sub-pixel included in the pixel. Then, based on the target grayscale value corresponding to the sub-pixel, generate the image data to be displayed and display it, which can effectively improve the resolution of the displayed image. Based on the above-mentioned inventive concept, the image display scheme in this application is designed.

[0077] The following is an example of an application scenario of the image display method provided by the present application.

[0078] Exemplarily, in this scenario, a user uses a field sequential display device to watch a video. After receiving the current frame image, the field sequential display device processes it as an image to be processed to improve the resolution and thus improve the display effect.

[0079] The field sequential display device splits the image to be processed to obtain multiple single-primary color images for subsequent field sequential display. Then, for each single-primary color image, the initial grayscale value corresponding to the pixel is determined.

[0080] Then, according to the initial grayscale value corresponding to the pixel point and the initial grayscale value corresponding to the pixel point adjacent to the pixel point, the target grayscale value corresponding to the sub-pixel point included in the pixel point is determined; then, according to the target grayscale value corresponding to the sub-pixel point, the image data to be displayed is generated; finally, the image data to be displayed is displayed according to the image data to be displayed. Each sub-pixel point corresponds to a different color, which can improve the resolution of the displayed image.

[0081] It should be noted that the above scenario is only an example of an application scenario provided by an embodiment of the present application. The embodiment of the present application does not limit the actual form of the various devices included in the scenario, nor does it limit the interaction method between the devices. In the specific application of the solution, it can be set according to actual needs.

[0082] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0083] Figure 4 This is a flow chart of the image display method provided in the present application. The execution subject of the method may be a field sequential display device. The method in this embodiment may be implemented by software, hardware, or a combination of software and hardware.

[0084] like Figure 4 As shown, the processor in the field sequential display device is configured to perform the following steps:

[0085] S401: receiving an image to be processed, and splitting the image to be processed to obtain multiple single-primary-color images.

[0086] In this step, after receiving the image to be processed, the video input interface or the wireless data transmission module in the field sequential display device transmits it to the processor for processing. The processor can split it into multiple single-primary-color images.

[0087] Exemplarily, the data corresponding to each pixel in the image to be processed is red, green and blue (RGB) data, and the RGB data is the grayscale value corresponding to the red primary color, the grayscale value corresponding to the green primary color, and the grayscale value corresponding to the blue primary color.

[0088] The grayscale value corresponding to the red primary color in the RGB data can be taken out as the initial grayscale value corresponding to the pixel point to obtain a single primary color image with red as the primary color.

[0089] The grayscale value corresponding to the green primary color in the RGB data is taken out as the initial grayscale value corresponding to the pixel point, and a single primary color image with green as the primary color is obtained.

[0090] The grayscale value corresponding to the blue primary color in the RGB data is taken out as the initial grayscale value corresponding to the pixel point, and a single primary color image with blue as the primary color is obtained.

[0091] S402: Determine an initial grayscale value corresponding to a pixel point according to the single primary color image.

[0092] After the processor obtains a plurality of single-primary-color images by splitting the image to be processed, for each single-primary-color image, the processor determines an initial grayscale value corresponding to each pixel point according to the single-primary-color image.

[0093] S403: Determine a target grayscale value corresponding to a sub-pixel included in the pixel point according to an initial grayscale value corresponding to the pixel point and initial grayscale values ​​corresponding to pixels adjacent to the pixel point.

[0094] After obtaining the initial grayscale value corresponding to each pixel, the processor can determine the target grayscale value corresponding to the sub-pixel points included in the pixel point according to the initial grayscale value corresponding to the pixel point and the initial grayscale values ​​corresponding to the pixel points adjacent to the pixel point.

[0095] First, a target sub-pixel point is determined from the sub-pixel points included in the pixel point; and then the initial grayscale value corresponding to the pixel point is used as the target grayscale value corresponding to the target sub-pixel point.

[0096] For sub-pixels to be configured except the target sub-pixel among the sub-pixels included in the pixel, a reference pixel corresponding to the sub-pixel to be configured is determined from pixel points adjacent to the pixel.

[0097] Then, based on the first distance between the sub-pixel to be configured and the target sub-pixel included in the pixel point, the second distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel point, the initial grayscale value corresponding to the pixel point, and the initial grayscale value corresponding to the reference pixel point, the target grayscale value corresponding to the sub-pixel to be configured is determined.

[0098] S404: Generate image data to be displayed according to the target grayscale value corresponding to the sub-pixel point.

[0099] After the processor obtains the target grayscale value corresponding to each sub-pixel point, it combines them to generate image data to be displayed.

[0100] The display screen is configured to: according to the image data to be displayed, control the backlight source corresponding to the primary color of the single primary color image to light up, and control the liquid crystal molecules corresponding to the sub-pixel points to deflect to the target angle.

[0101] The processor transmits the image data to be displayed to the TCON board in the display screen. The TCON board converts the image data to be displayed, obtains the driving data and transmits it to the LCD panel, drives the backlight source corresponding to the primary color of the single-primary-color image to light up, drives the liquid crystal in the LCD panel to deflect to the corresponding angle, and the monochrome backlight emitted by the backlight source passes through the liquid crystal molecules to display the corresponding color, and then the display screen can display the single-primary-color image.

[0102] The field sequential display device provided in this embodiment includes a display screen and a processor; the processor is configured to split the image to be processed after acquiring the image to be processed to obtain multiple single-primary-color images; and then for each single-primary-color image, determine the initial grayscale value corresponding to each pixel according to the single-primary-color image. Then, after determining the target grayscale value corresponding to the sub-pixel included in each pixel based on the initial grayscale value corresponding to each pixel, the initial grayscale value corresponding to the pixel adjacent to each pixel, and the target grayscale value corresponding to the sub-pixel included in each pixel, the image data to be displayed is generated. Finally, the display screen controls the backlight source corresponding to the primary color of the single-primary-color image to light up according to the image data to be displayed, and controls the liquid crystal molecules corresponding to the sub-pixel to deflect to the target angle to display the image. This solution determines the target grayscale value corresponding to the sub-pixel included in the pixel, so that the same target value pixel can display multiple colors, effectively improving the resolution of the displayed image and improving the display effect.

[0103] The following describes a situation in which, before the processor splits the image to be processed, it can also obtain the operation mode and then determine the target grayscale value corresponding to the sub-pixel point in combination with the operation mode.

[0104] Before the processor splits the image to be processed to obtain multiple single-primary-color images, it obtains the image to be processed and the operation mode; after obtaining the multiple single-primary-color images, the target grayscale value corresponding to the sub-pixel point can be determined in combination with the operation mode.

[0105] The operating mode is a first operating mode or a second operating mode, the first operating mode represents a mode operating at a preset refresh rate, and the second operating mode represents a mode operating at a refresh rate N times the preset refresh rate, where N is greater than 1.

[0106] It should be noted that the preset refresh rate can be 60 Hz, 120 Hz, 240 Hz, etc. The embodiment of the present application does not limit the preset refresh rate and can be set according to actual conditions.

[0107] If the operation mode is the second operation mode, the pixel points are divided into target row pixel points belonging to the target row and non-target row pixel points not belonging to the target row.

[0108] It should be noted that the target row is an odd-numbered row or an even-numbered row.

[0109] When the operating mode is the second operating mode, the dual line gate (Dual Line Gate, DLG) technology or hardware super resolution (HSR) technology can be used to achieve a high refresh rate. DLG technology reduces the vertical pixel rendering accuracy, only renders the target row, and then copies the target row data to the non-target row for display. For example, only renders 1, 3, 5, and 7 rows, copies the data of the first row to the second row, and copies the data of the third row to the fourth row, and so on. At this time, the number of vertical refreshes required is reduced by half, so the refresh time is reduced by half compared to the original, so the refresh rate of the display can be improved.

[0110] The basic principle of HSR technology is similar to that of DLG, which is to compress vertical pixels and only render the target row, while the non-target row is displayed by fusing the information of two adjacent rows. Therefore, compared with DLG technology, the picture using HSR technology will make the color and line transition of the whole picture more natural after fusing the even-numbered rows of pixels, and the clarity will be improved accordingly.

[0111] Furthermore, the target grayscale value corresponding to the sub-pixel points included in the pixel point in the target row can be determined according to the initial grayscale value corresponding to the pixel point in the target row and the initial grayscale values ​​corresponding to the pixel points adjacent to the pixel point in the target row.

[0112] The target grayscale value corresponding to the sub-pixel points included in the non-target row pixel point is determined according to the initial grayscale value corresponding to the pixel points adjacent to the non-target row pixel point.

[0113] Specifically, a preset high refresh rate method may be used to determine the target grayscale value corresponding to each sub-pixel point in the non-target row of pixels.

[0114] It should be noted that the preset high refresh rate method is the DLG method or the HSR method. When the DLG method is used, the target grayscale value of the sub-pixel point in the target row is used as the target grayscale value of the sub-pixel point in the non-target row.

[0115] For example, if the target row is an odd-numbered row, the target grayscale value of the sub-pixel in the first row is used as the target grayscale value of the sub-pixel in the second row, and the target grayscale value of the sub-pixel in the third row is used as the target grayscale value of the sub-pixel in the fourth row, and so on. The target grayscale value of the sub-pixel in each non-target row can be obtained.

[0116] When using the HSR method, for each non-target row, the target grayscale value of the pixel points in the adjacent target row is used for fusion calculation to obtain the target grayscale value of the pixel points in the non-target row.

[0117] For example, if the target row is an odd row, the target grayscale value of the sub-pixel in the first row and the target grayscale value of the sub-pixel in the third row are used as the target grayscale value of the sub-pixel in the second row. The fusion method is the fusion method in the HSR technology.

[0118] If the operation mode is the first operation mode, the pixels are not divided into target row pixels and non-target row pixels, and the target grayscale value corresponding to the sub-pixels included in the pixel is determined based on the initial grayscale value corresponding to the pixel and the initial grayscale value corresponding to the pixels adjacent to the pixel.

[0119] The field sequential display device provided in this embodiment divides the pixel points into target row pixel points and non-target row pixel points when the operation mode is the second operation mode, and then adopts different methods to determine the target grayscale values ​​corresponding to the sub-pixel points included in the two. When the operation mode is the first operation mode, the target grayscale values ​​corresponding to the sub-pixel points included in the pixel point are directly determined based on the initial grayscale values ​​corresponding to the pixel point and its adjacent pixel points. According to different operation modes, the target grayscale values ​​corresponding to the sub-pixel points included in the pixel point are determined, so that the determined target grayscale values ​​are more accurate.

[0120] Furthermore, based on the above-mentioned embodiment, the embodiment of the present application describes the situation in which the processor determines the target grayscale value corresponding to each sub-pixel when the operating mode is the first operating mode. Figure 5 Schematic diagram of the process of determining the target grayscale value corresponding to each sub-pixel provided in this application Figure 1 , wherein the processor in the field sequential display device is configured to perform the following steps:

[0121] S501: Determine a target sub-pixel point from sub-pixel points included in a pixel point.

[0122] After the processor obtains the initial grayscale value corresponding to each pixel, if the acquired operation mode is the first operation mode, it is not necessary to divide the pixel into target row pixel and non-target row pixel. For each pixel, the target sub-pixel is determined from the sub-pixels included in the pixel.

[0123] It should be noted that the method for determining the target sub-pixel point may be to randomly select a sub-pixel point from the sub-pixels included in the pixel point as the target sub-pixel point.

[0124] The method for determining the target sub-pixel point may also be to use the sub-pixel point corresponding to the single primary color among the sub-pixels included in the pixel point as the target sub-pixel point.

[0125] The method for determining the target sub-pixel point may also be to use a sub-pixel point located at the center of the sub-pixels included in the pixel point as the target sub-pixel point according to the arrangement layout of the sub-pixels.

[0126] The embodiment of the present application does not limit the method for determining the target sub-pixel point, and it can be determined according to actual conditions.

[0127] S502: Using the initial grayscale value corresponding to the pixel as the target grayscale value corresponding to the target sub-pixel.

[0128] After the processor determines the target sub-pixel point, the initial grayscale value corresponding to the pixel point can be used as the target grayscale value corresponding to the target sub-pixel point.

[0129] S503: For sub-pixels to be configured except the target sub-pixel among the sub-pixels included in the pixel, determine reference pixels corresponding to the sub-pixels to be configured from pixels adjacent to the pixel.

[0130] After the processor determines the target sub-pixel point, for each sub-pixel point to be configured except the target sub-pixel point among the sub-pixels included in the pixel point, a reference pixel point corresponding to the sub-pixel point to be configured is determined from the pixel points adjacent to the pixel point.

[0131] It should be noted that the reference pixel point may be selected by selecting a pixel point that is closest to the pixel point from pixels adjacent to the pixel point as the reference pixel point.

[0132] Another method of selecting a reference pixel point is to randomly select a pixel point from pixels adjacent to the pixel point as the reference pixel point.

[0133] The reference pixel point may also be selected by determining the pixel points that belong to the same row as the pixel point from the pixel points adjacent to the pixel point, and then randomly selecting a pixel point from these pixel points as the reference pixel point.

[0134] The embodiment of the present application does not limit the method of selecting reference pixels, which can be determined according to actual conditions.

[0135] S504: Determine the target grayscale value corresponding to the sub-pixel to be configured based on the first distance between the sub-pixel to be configured and the target sub-pixel included in the pixel point, the second distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel point, the initial grayscale value corresponding to the pixel point, and the initial grayscale value corresponding to the reference pixel point.

[0136] After the reference pixel is determined, the target grayscale value corresponding to the sub-pixel to be configured can be determined based on the first distance between the sub-pixel to be configured and the target sub-pixel included in the pixel, the second distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel, the initial grayscale value corresponding to the pixel, and the initial grayscale value corresponding to the reference pixel.

[0137] Specifically, first, according to the magnitude relationship between the first distance and the second distance, the first weight corresponding to the pixel point and the second weight corresponding to the reference pixel point are determined. If the first distance is greater than or equal to the second distance, the first weight is greater than or equal to the second weight; if the first distance is less than the second distance, the first weight is less than the second weight, and the sum of the first weight and the second weight is 1.

[0138] Then, the product of the initial grayscale value corresponding to the pixel and the first weight and the product of the initial grayscale value corresponding to the reference pixel and the second weight are added together to obtain the target grayscale value corresponding to the sub-pixel to be configured.

[0139] For example, for a single primary color image corresponding to the primary color red, the formula Calculate the target grayscale value corresponding to the sub-pixel to be configured, where R′ ij Indicates the target grayscale value corresponding to the sub-pixel to be configured, R ij Represents the initial grayscale value corresponding to the pixel, R i(j+1) Represents the initial grayscale value corresponding to the reference pixel. is the first weight corresponding to the pixel, is the second weight corresponding to the reference pixel.

[0140] For example, based on the above example, Figure 6 The color data of the sub-pixel points corresponding to the single-primary color image determined according to the target grayscale value provided in this application Figure 1 ,like Figure 6 As shown, * ij Indicates the target gray value corresponding to the target sub-pixel, *′ ij and*" ij It represents the target grayscale value corresponding to the sub-pixel to be configured. It can be seen that the sub-pixels included in a pixel have different grayscale values, and can display multiple colors with higher resolution.

[0141] It should be noted that, if the reference pixel is not determined by the method of selecting the reference pixel, the initial grayscale value corresponding to the pixel may be used as the target grayscale value corresponding to the sub-pixel to be configured.

[0142] The field sequential display device provided by the present embodiment divides the sub-pixels included in the pixel point into target sub-pixels and sub-pixels to be configured when the operating mode is the first operating mode, and then uses the initial grayscale value corresponding to the pixel point as the target grayscale value corresponding to the target sub-pixel point; determines the target grayscale value corresponding to the sub-pixel point to be configured according to the two distances from the target sub-pixel point included in the pixel point and the reference pixel point, and the initial grayscale value of the pixel point and the reference pixel point, so that the target grayscale value corresponding to the determined sub-pixel point is more accurate, and when the sub-pixel point is displayed according to the target grayscale value, the display effect is better and the color transition is smoother.

[0143] Furthermore, based on the above-mentioned embodiment, the embodiment of the present application describes the situation in which the processor determines the target grayscale value corresponding to each sub-pixel point included in the target row pixel point when the operating mode is the second operating mode. Figure 7 Schematic diagram of the process of determining the target grayscale value corresponding to each sub-pixel provided in this application Figure 2 , wherein the processor in the field sequential display device is configured to perform the following steps:

[0144] S701: Determine a target sub-pixel point from sub-pixel points included in a pixel point.

[0145] S702: Using the initial grayscale value corresponding to the pixel point in the target row as the target grayscale value corresponding to the target sub-pixel point included in the pixel point in the target row.

[0146] S703: For sub-pixels to be configured except the target sub-pixel among the sub-pixels included in the target row of pixels, determine reference pixels corresponding to the sub-pixels to be configured from pixels adjacent to the target row of pixels.

[0147] It should be noted that the above steps S701 to S703 are similar to steps S501 to S503 in the second embodiment, and will not be described in detail here.

[0148] S704: Determine the target grayscale value corresponding to the sub-pixel to be configured based on the third distance between the sub-pixel to be configured and the target sub-pixel included in the target row of pixels, the fourth distance between the sub-pixel to be configured and the target sub-pixel included in the reference pixel, the initial grayscale value corresponding to the target row of pixels, and the initial grayscale value corresponding to the reference pixel.

[0149] After the processor obtains the reference pixel point, it can determine the target grayscale value corresponding to the sub-pixel point to be configured based on the third distance between the sub-pixel point to be configured and the target sub-pixel point included in the target row of pixels, the fourth distance between the sub-pixel point to be configured and the target sub-pixel point included in the reference pixel point, the initial grayscale value corresponding to the target row of pixels, and the initial grayscale value corresponding to the reference pixel point.

[0150] Specifically, firstly, according to the relationship between the third distance and the fourth distance, the third weight corresponding to the target row pixel and the fourth weight corresponding to the reference pixel are determined. If the third distance is greater than or equal to the fourth distance, the third weight is greater than or equal to the fourth weight; if the third distance is less than the fourth distance, the third weight is less than the fourth weight, and the sum of the third weight and the fourth weight is 1.

[0151] Then, the product of the initial grayscale value corresponding to the pixel point in the target row and the third weight and the product of the initial grayscale value corresponding to the reference pixel point and the fourth weight are added together to obtain the target grayscale value corresponding to the sub-pixel point to be configured.

[0152] It should be noted that if the reference pixel is not determined by the method of selecting the reference pixel, the initial grayscale value corresponding to the pixel in the target row may be used as the target grayscale value corresponding to the sub-pixel to be configured.

[0153] For example, based on the above example, Figure 8 The color data of the sub-pixel points corresponding to the single-primary color image determined according to the target grayscale value provided in this application Figure 2 ,like Figure 8 As shown, * ij Indicates the target gray value corresponding to the target sub-pixel, *′ ij and*" ij Indicates the target grayscale value corresponding to the sub-pixel to be configured, *′ ij ~ and *″ ij ~ represents the target grayscale value corresponding to the sub-pixel point in the non-target row pixel point. It can be seen that the grayscale values ​​of the sub-pixels included in a pixel point are different, and multiple colors can be displayed with higher resolution.

[0154] The field sequential display device provided in the present embodiment divides the pixel points into target row pixel points and non-target row pixel points, and then divides the target row pixel points into target sub-pixel points and sub-pixel points to be configured, and then determines the target grayscale values ​​corresponding to the two sub-pixel points, so that the target grayscale values ​​corresponding to the determined sub-pixel points are more accurate, and when the sub-pixel points are displayed according to the target grayscale values, the display effect is better and the color transition is smoother.

[0159] Generate image data to be displayed according to the target grayscale value corresponding to the sub-pixel point;

[0160] According to the image data to be displayed, the backlight source corresponding to the primary color of the single primary color image is controlled to light up, and the liquid crystal molecules corresponding to the sub-pixel points are controlled to deflect to the target angle.
